AFWFilters Electric Shut Off (ESO) Switch Kit for Aquatec Booster Pumps

I purchased the Electric Shutoff Switch (ESO) for my 50 GPD 5-Stage Reverse Osmosis system, along with the Aquatec 6800 Booster Pump Kit. Before, my feed pressure into the RO system was between 30 and 40 psi, which wasn't enough to push water into the holding tank. I was constantly running out of water, and it was really frustrating. I tried everything: changing filters, replacing the membrane, and even getting a new backflow valve. But it became clear that the pressure was just too low for the system to run properly. Adding this pump was super easy with the provided instructions. Now, my pressure gauge shows about 60 psi, and I haven’t run out of water since. The water pressure coming out of the spigot is also much higher, making it quick to fill up a pitcher. The Electric Shutoff Switch is a great addition. It lets the system "rest" between cycles and stops it from continuously wasting water like before. The pump is very quiet, and with the sink cupboard doors shut, I can't hear it at all when it comes on. This has been the perfect fix for my RO system, and my whole family loves the fresh, clean water.

Planning on installating this and although the description clearly states that instructions are included, none were.

Must have for any under sink water filtration system with a booster pump. Unless you like hearing the pump run constantly and water go down the drain constantly. If that's your thing, don't buy this anti-headache device. Works excellent so far, after six months. Do recommend

Was having problems with my ASO valve when paired with a booster pump. ASO valves don't open with a high end pressure input while the low end was in the cut-in range (was opening at 2-4 PSI lower, causing constant run of the rump and water waste). This ESO ensures the valve always opens and closes at the right time (since it shares the same TSO circuit) 10/10 would ESO again.

No electrical specification for this solenoid other than working voltage. Manufacturer's website ksd.com.tw also none. Documentation is identical as comes with pump, just how to hook up a generic ESO, so nothing specific to the solenoid. Was concerned about power drain but monitoring with the transformer plugged into a Kill A Watt meter showed only around 4 watts extra for the solenoid over the 13-15 watts the pump used. No mounting flanges, just a couple of holes on the underside. Guess I'll need to mount it screwed to a small block of wood, right now it's hanging from the pump 😔 It works as advertised with the above caveats. The jury is out on how long it will last.
